Joseph Henry's Notebook, Sound and Weather, 1865-1866

Always ready to jot down his thoughts concerning his experiments, Joseph Henry, first Secretary of the Smithsonian Institution carried pocket notebooks with him. Written while the country was beginning its period of post-Civil War reconstruction, this pocket notebook contains his notes about sound, ear trumpets, weather (particularly fog), lighthouses, and engines. There's also an element of practicality, too, when it comes to how he made his notes. It starts at the beginning and proceeds to the middle. At that point, Henry turned the book over and proceeded to make the rest of his notes starting from the back cover. Are you up to the challenge? Hint: As you help us transcribe Henry's notes, you will want to use our image rotate function when you transcribe pages from this second half.
